“…Estes amidos poderiam substituir féculas modificadas quimicamente ou abrir novos mercados para amidos (LEONEL, 2007). A mandioquinha-salsa apresenta amidos ausentes de fatores anti-nutricionais e baixos teores de amilopectina, características que favorecem alta digestibilidade (NUNES et al, 2010).…”

“…The are several studies on the extraction and characterization of starch in literature, as well as on the relationship between the extraction processes and molecular structure of the final product (LEONEL, 2007;DENARDIN & SILVA, 2009). Studies on the optimization of the extraction process, are still an open issue in literature and is the focus of the present contribution.…”

“…A more recent application has been in the development of biomaterials (APLEVICZ & DEMIATE, 2007;ARAUJO-FARRO et al, 2010). Research institutions and industries, therefore, are becoming more interested in identifying native starches with specific characteristics, as well as improving the extraction process towards greater purity and yield (LEONEL, 2007).…”

ABSTRACT:The objective was to study the starch extraction process of the peach palm (Bactris gasipaes Kunth.) fruit focused on increasing yield and in preserving the quality characteristics the extracted product. Two experimental designs are carried out in order to investigate the effects of NaOH and NaHSO3 concentrations, as well as the decantation time, on the yield of starch and on product color. Firstly, a 2 3 full factorial design provided a linear model with 95% of confidence, indicating major tendencies for optimization. Secondly, a 2 2 central composite design rendered a quadratic model which allowed the maximization of yield (it 9.0% higher) without compromising the color of the product. The maximum yield of 23.90%, validated with triplicate experiments, is considerably higher than the yield of starch from other fruits reported in literature.

The objective of this study was to evaluate the efficiency of time scarification of seeds in sulfuric acid to break the dormancy of seeds, seedling emergence and post-seminal morphology of Canna edulis. This way, were determined biometric characteristics of seeds. To dormancy breaking, the seeds were immersed in sulfuric acid 98% during 0.0, 0.5, 1.0, 1.5, 2.0 and 2.5 hours and sown in sand in a condition greenhouse. After 21 days emergence percentage, emergence speed index (IVE), shoot length and seedling dry weight of plants were recorded. Periodically, digital images was taken and performed the seedlings morphological characterization. The fruit of Canna edulis contains an average of 19.27 globoses seeds of black coloration measuring about 5.62 mm in diameter, the average weight of 1000 seeds is 128.8 grams. The highest percentage of seedling emergence of 60% and 90% are obtained from seed treated with 0.5 hours in sulfuric acid at 10 and 21 days after sowing, respectively. The seeds have hypogeal germination with development of fasciculate roots with root axes differentiated at 4 days after sowing. The protophyll is observed from the eighth day and the seedlings have intense purple coloration at 16 days after sowing. Keywords: Cannaceae, physical dormancy, coat seeds, post-seminal development. RESUMOÁcido sulfúrico na quebra de dormência de sementes e na emergência e morfologia de plântulas de Canna edulis O objetivo deste trabalho foi avaliar a eficiência do tempo de imersão das sementes em ácido sulfúrico na quebra de dormência de sementes, emergência de plântulas e morfologia pós-seminal de Canna edulis. Assim, foram determinadas características biométricas das sementes. Para superação da dormência, as sementes foram imersas em ácido sulfúrico 98% durante 0,0; 0,5; 1,0; 1,5; 2,0 e 2,5 horas sendo posteriormente semeadas em areia em condição de estufa. Aos 21 dias após a semeadura calculou-se a porcentagem de emergência, índice de velocidade de emergência (IVE), comprimento de parte aérea e massa seca de plântulas. Periodicamente após a semeadura foram capturadas imagens digitais de plântulas e caracterizadas a morfologia. Os frutos de Canna edulis contém em média 19,27 sementes globosas de coloração preta medindo cerca 5,62 mm de diâmetro, cujo peso médio de 1000 sementes é de 128,8 gramas. As maiores porcentagens de emergência de plântulas de 60% e 90% são obtidas de semente tratadas por 0,5 horas em ácido sulfúrico aos 10 e 21 dias, respectivamente. As sementes apresentam germinação hipógia com desenvolvimento de sistema radicular fasciculado com eixos radiculares diferenciados após 4 dias de semeadura. O protofilo é observado a partir do oitavo dia e as plântulas apresentam coloração púrpura intensa a partir de 16 dias da semeadura. Palavras-chaves: Cannaceae, dormência física, escarificação, desenvolvimento pós-seminal.(1)
